python passlib生成Hash密文并进行验证--Hash a password with passlib

encrypt()

verify()

identify()

>>> # attempting to call verify() with another algorithm's hash will result in a ValueError:
>>> from passlib.hash import sha256_crypt, md5_crypt
>>> other_hash = md5_crypt.encrypt("password")
>>> sha256_crypt.verify("password", other_hash)
Traceback (most recent call last):
<traceback omitted>
ValueError: not a valid sha256_crypt hash

>>> # this can be prevented by using the identify method,
>>> # determines whether a hash belongs to a given algorithm:
>>> hash = sha256_crypt.encrypt("password")
>>> sha256_crypt.identify(hash)
True
>>> sha256_crypt.identify(other_hash)
False
